So besides the extruder/stepper what else is needed to make this modification? All cables wiring plug and play? If using the smaller stepper does there still need to be adjustments made to the firmware for E-Steps? You listed a couple different steppers in this thread or is one for the destructive top and a different one for the non-destructive top? Sorry for all the questions but yea Im a 3D printing newb. Thanks! awesome stuff here!
